Resently I discovered that one of my core routers has a network statement in multiple area (ie Area0 and Area1). At this time, there appears to be no problems. Here is a sample of what I found:
(Obviously IP's have been altered to protect the inocent)
network 10.10.58.0 0.0.0.255 area 0
network 10.10.96.0 0.0.31.255 area 1
network 10.10.128.0 0.0.31.255 area 1
network 10.10.253.0 0.0.0.255 area 1
network 10.10.224.0 0.0.31.255 area 0
As you will note network 10.10.253.0 0.0.0.255 area 1
is also included in network 10.10.224.0 0.0.31.255 area 0
due to the masking. I am not sure why it being used, but I would think there is some violation here.
Is this acceptable?
